Eurybia conspicua is a western boreo-montane taxon; it ranges from the Interior Mountains and Plateaus to the Rocky Mountains, and spreads onto the northern Great Plains in the aspen parklands-southern boreal forests of Canada, barely into western Manitoba. It is disjunct to the Black Hills (South Dakota) and Cypress Hills (Alberta-Saskatchewan). It stops at the Canadian Shield due to soil preferences (A. J. Breitung 1988). This taxon has the highest chromosome number in the genus.

More info for the term:
herbWestern showy aster is a native, perennial herb. Its peduncle is 1 to 2 feet
(30-60 cm) tall, and it usually has several shorter sterile stems
arising from extensive creeping rhizomes [
14]. Rhizomes grow 0.5 to 2.0
inches (0.5-5 cm) below the soil surface [
4]. Flowers are borne in an
open, flat-topped inflorescence [

Fire Ecology

More info for the terms:
fire regime,
seedWestern showy aster is moderately resistant to fire, typically sprouting from
surviving rhizomes. Rhizomes usually survive light- to
moderate-severity fires that do not cause excessive soil heating [
4,
8].
After fire, western showy aster also regenerates from wind-dispersed and
soil-stored seed [
5,
20,
24]. Growth is stimulated after fire, resulting
in mass flowering in the first few postfire years [

Habitat characteristics
(
الإنجليزية
)
المقدمة من Fire Effects Information System Plants
Western showy aster occurs in continental boreal and cool-temperate climates on
moderately dry soils. It is a common interior species on "water
shedding" sites [
12]. It is most common in montane zones, but is also
found in forested areas of valley and lower subalpine zones [
14]. In
Wyoming western showy aster occurs from 5,500 to 9,000 feet (1,667-2,727 m)
elevation. In Montana it is found from 3,000 to 7,100 feet (910-2,152
m) elevation [

More info for the terms:
cover,
forest,
frequency,
moderate-severity fireWestern showy aster increases rapidly after fire [
16,
18]. Western showy aster exhibits
mass flowering in postfire years 1 and 2. The extent of flowering is
directly related to prefire abundance and postfire survivorship
[
22,
23,
24]. Western showy aster frequency increased from 8 percent before fire
to 20 percent 2 years after a moderate-severity fire in a Douglas-fir
forest in Idaho. By postfire year 7, western showy aster frequency increased to
52 percent [
16]. Following the 1977 Pattee Canyon Fire in Missoula,
Montana, western showy aster cover was 1.4 percent in 1978 and 2.0 percent in
1982 [
16].
On ponderosa pine and Douglas-fir communities in the Blue Mountains
of northeastern Oregon, western showy aster frequency and cover were higher on
sites that had been thinned 6 years previously than on prescribed burned,
thinned-and-burned, or control sites. Western showy aster was determined to be
an indicator species for thinned sites (P≤0.05). For further information
on the effects of thinning and burning treatments on western showy aster and 48
other species, see the
Research Project Summary of Youngblood and others'
[

Western showy aster is tolerant of both sun and shade. Small colonies typically
establish following stand-destroying fires or clearcutting and site
scarification [
20,
22]. Western showy aster produces more vegetative growth and
fewer flowering stems with increasing shade in later succession [
14].
It can, however, maintain extensive colonies beneath pine (Pinus spp.)
and open Douglas-fir canopies. It is an indicator of late seres in
Douglas fir/ninebark (Physocarpus malvaceus) habitat types of central
Idaho [

Eurybia conspicua: Brief Summary
(
الإنجليزية
)
المقدمة من wikipedia EN
Eurybia conspicua, commonly known as the western showy aster, is a North American species of plants in the family Asteraceae. It is native to western Canada (from Manitoba to British Columbia) and the western United States (northern Cascades, northern Rockies, Black Hills, and other mountains of Washington, Oregon, Idaho, Montana, Wyoming, and South Dakota).
Eurybia conspicua is a perennial spreading by means of underground rhizomes, thus forming loose clonal colonies. Each plant can produce a flat-topped array of 5-50 flower heads, each head with 12–35 blue or violet ray florets surrounding 48–55 yellow disc florets.
